Employement lifetime measurement

Our scientific model

The main pillars of our methodology are the Russels Circumplex model and the Employee Happiness Model. With the Russels Circumplex model, we measure the mood and stress within the organization. The Employee Happiness Model assesses underlying reasons for mood but also measures satisfaction and engagement. The Employee Happiness Model is scientifically based on the Job Demands-Resources theory (Bakker & Demerouti, 2006) and Herzberg's motivation theory. Additionally, all motivations are substantiated in various scientific studies concerning job happiness, turnover and absenteeism.

With the Russels Circumplex model, we measure the mood and stress in the organization. 2DAYSMOOD can make a positive contribution to organizations through continuous mood measurement. With our solution, you get valuable data on the mood of employees and the underlying reasons at the team level. Employees give their feedback 100% anonymously, in 15 seconds and with a fun ending.
